Summary
Converts time values recorded in a date field from one time zone to another time zone.
Converting time values from one time zone to another helps normalize temporal data from different time zones. This improves display and query performance for visualizing temporal data from different time zones using the Time Slider.

Illustration
Usage
The input time values to be converted must be stored in a Date field.
The added output time field will be a Date type field.
If your data was collected in a time zone which observes Daylight Saving, then you should choose the parameters to honor Daylight Saving time in the input and output fields. Learn more about Daylight Saving Time.
Syntax
ConvertTimeZone_management (in_table, input_time_field, input_time_zone, output_time_field, output_time_zone, {input_dst}, {output_dst})| Parameter | Explanation | Data Type |
in_table | The input feature class or table that contains the time stamps which will be transformed to a different time zone. | Table View |
input_time_field | The input field that contains the time stamps which will be transformed to a different time zone. | Field |
input_time_zone | The input time zone in which the time stamps were collected. | String |
output_time_field | The output field in which the time stamps transformed to the desired output time zone will be stored. | String |
output_time_zone | The time zone to which the time stamps will be transformed. By default, the output time zone is the same as the input time zone. | String |
input_dst (Optional) | Indicates whether the time stamps were collected while observing Daylight Saving Time rules in the input time zone. When reading the time values to convert the time zone, the time values will be adjusted to account for the shift in time during Daylight Saving Time. By default, the input time values are adjusted to account for the shift in time due to the Daylight Saving Time rules in the input time zone.
| Boolean |
output_dst (Optional) | Indicates whether the output time values will account for the shift in time due to the Daylight Saving Time rules observed in the output time zone. By default, the output time values are adjusted to account for the shift in time due to the Daylight Saving Time rules observed in the output time zone.
| Boolean |
Code sample
ConvertTimeZone example (Python window)
The following Python window script demonstrates how to use the ConvertTimeZone tool in immediate mode.
import arcpy
arcpy.ConvertTimeZone_management("C:/Data/TemporalData.gdb/InputData","Input_Time","Pacific_Standard_Time","Output_Time","Eastern_Standard_Time","INPUT_ADJUSTED_FOR_DST","OUTPUT_ADJUSTED_FOR_DST")
ConvertTimeZone example (stand-alone script)
The following stand-alone script demonstrates how to use the ConvertTimeZone tool.
# Name: ConvertTimeZone_Ex02.py
# Description: Convert a time field to another time zone
# Requirements: None
# Import system modules
import arcpy
# Set local variables
inTable = "C:/Data/TemporalData.gdb/InputData"
inputTimeField = "Input_Time"
inputTimeZone = "Pacific_Standard_Time"
outputTimeField = "Output_Time"
onputTimeZone = "Eastern_Standard_Time"
inputUseDaylightSaving = "INPUT_ADJUSTED_FOR_DST"
outputUseDaylightSaving = "OUTPUT_ADJUSTED_FOR_DST"
# Execute CalculateEndDate
arcpy.ConvertTimeZone_management(inTable, inputTimeField, inputTimeZone, outputTimeField, onputTimeZone, inputUseDaylightSaving, outputUseDaylightSaving)
